Your benefits

Fieldgate SWG70 is a gateway for WirelessHART
networks. It enables WirelessHART field devices to communicate with each other and manages network security and connectivity. Fieldgate converts and saves the wireless field device data
to a format that is compatible with other systems.
It has Ethernet and serial interfaces to connect to host applications such as SCADA tools.

• Easy commissioning and diagnosis of a self-organized
WirelessHART network• Seamless integration of field device information into higherorder system applications using standardized protocols suchas MODBUS, EtherNet/IP, HART-IP or OPC• Wireless configuration and management of smart fielddevices in a facility using FieldCare• Flexible use of Fieldgate in hazardous areas of a facilityWirelessHART Fieldgate SWG70

Function and system design
WirelessHART

WirelessHART adds wireless capabilities to the HART protocol, while guaranteeing compatibility withexisting HART devices, commands and tools.
A WirelessHART network comprises:• WirelessHART field devices• Wired field devices with a connected WirelessHART Adapter• Fieldgate
The WirelessHART protocol may not be used to replace the wiring in the case of safety applications
with a control function.

WirelessHART Fieldgate
SWG70

The WirelessHART Fieldgate SWG70 acts as an interface between the WirelessHART network and asystem that has an Ethernet or RS-485 connection.
The WirelessHART Fieldgate SWG70 supports the following functions:• Wireless network configuration and management• Acquisition of data from the field devices and presentation to connected systems• MODBUS, HART, HART-IP, OPC and EtherNet/IP support for system integration• Configuration of network, Fieldgate and field devices via Web interface or FDT/DTM.
Fieldgate is designed for installation in hazardous areas Zone 2. You can mount the antenna directlyon the Fieldgate or remotely depending on the requirements of the application.

System design

The WirelessHART Fieldgate stores information received from the WirelessHART Adapter SWA70or other WirelessHART field devices in a buffer which can be accessed by a host application via anEthernet or RS-485 connection. The figure shows a Fieldgate operating in a typical meshed WirelessHART network architecture.

area:

Avoid mounting the WirelessHART Fieldgate near a pipe or high-voltage equipment
wherever possible.
Where possible, the WirelessHART Fieldgate should be in radio contact with at least
20 % of all wireless field devices or adapters.
Under typical conditions, the maximum spacing is 250 m outdoors and 50 m indoors.
A remote antenna can be mounted outside a cabinet.
With vertical antenna.
If there is a risk of lightning, install suitable antenna accessories. See “Accessories” onpage 7.
Connect the protective ground to the protective ground connection of the Fieldgate
housing. The minimum cross-section of the protective ground is 2.5 mm2.
Fieldgates with the appropriate certification (see ordering information) can bemounted in Zone 2.
The housing cover can be removed in Zone 2 to view the LEDs. It is not permitted tooperate any switches in an explosive atmosphere.

Accessories
Antenna accessories

Note the following when selecting accessories for the antenna:• The Ex approval for Fieldgate SWG70 is only valid for the 2 dBi antenna supplied.
• The antenna must comply with the rules for the usage of 2.4 GHz equipment that apply in thecountry of installation. In case of doubt, please contact a regional expert for radio approvals.
• The gain is calculated from the difference in the antenna gain and the losses of the individualcomponents such as the cables and surge arrester. The gain may not exceed the 2 dBi limit.
• The WirelessHART range of the Fieldgate SWG70 depends on the coaxial cable used (attenuation)
between the Fieldgate and the antenna.
